Hi I'm having the following problem. When I do a tcp connect portscan to a remote host using the following: nmap -sT xxx.xxx.xxx.xxx -P0 -p 80 .... I get the the right response: Starting nmap V. 3.75 ( www.insecure.org/nmap ) Interesting ports on (xxx.xxx.xxx.xxx): Port State Service 80/tcp open http Port shows open...no problems..so far so good Now when I try to do a syn scan using the following: nmap.exe -sS xxx.xxx.xxx.xxx -P0 -p 80 I get a response saying the port is filtered. Starting nmap V. 3.75 ( www.insecure.org/nmap ) Interesting ports on (xxx.xxx.xxx.xxx): Port State Service 80/tcp filtered http Reading through the archives I found what looks to be the same problem I'm having: http://seclists.org/lists/nmap-dev/2005/Jan-Mar/0022.html I'm running the same version of nmap on my winxp workstation and have no problems. Both the win2003 server and my workstation are behind the same firewall hitting the same ruleset. Also, the win2003 server has the lastest updates from MS along with my workstation including SP2. Any ideas or suggestions would be most appreciated. Thanks in advance Bill Crenshaw __________________________________ Do you Yahoo!?
